Mate has a S40 98 model & when he unlocks the car with the fob there is
a second or so delay between - button press & clunk,doors open.

He pressed the fob & before the clunk he tried to open the boot.

The boot release button stayed pressed in & the only way he could get it
to pop back out was by inserting the key & wiggling it out.

However,whilst doing this he heard a 'ping' & know the release button goes
in & out with no resistance it also doesnt open the boot anymore.

Any suggestion on a quick fix or is it a crow bar job & a new bootlid?
